Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMBJ90CE3/TR13 is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Reverse standoff voltage: 90V (nominal)
• Breakdown voltage minimum: 100V
• Bidirectional channel configuration: 1 channel
• Peak pulse power rating: 600W
• General-purpose application classification
• Zener diode type

Mechanical Compatibility Criteria:

• Package type: DO-214AA / SMB form factor
• Surface-mount mounting technology
• Tape and reel packaging format

Regulatory & Environmental Criteria:

• RoHS3 compliance
• REACH unaffected status
• Moisture sensitivity level: 1 (unlimited shelf life)
• Active product status

Substitute parts SMBJ90CA (MDD manufacturer) and SMBJ90CA-13-F (Diodes Incorporated) satisfy all mandatory electrical and mechanical parameters. Variations in clamping voltage (146V vs. 160V) and peak pulse current (4.1A vs. 3.8A) remain within acceptable tolerance ranges for general-purpose TVS applications while maintaining identical standoff and breakdown voltage specifications.

Parameter Comparison

Engineering Selection Recommendations

All three components—SMBJ90CE3/TR13 (Microchip Technology), SMBJ90CA (MDD), and SMBJ90CA-13-F (Diodes Incorporated)—maintain active product status and full compliance with RoHS3 and REACH regulations. Each component carries MSL Level 1 classification, indicating unlimited shelf life without moisture sensitivity constraints.

Primary Selection Criteria:

The SMBJ90CE3/TR13 provides the highest clamping voltage specification at 160V maximum, suitable for applications requiring maximum transient suppression margin. The SMBJ90CA and SMBJ90CA-13-F variants offer clamping at 146V with marginally higher peak pulse current (4.1A vs. 3.8A), maintaining identical standoff and breakdown voltage performance.

Operating temperature ranges differ slightly: the SMBJ90CE3/TR13 extends to -65°C minimum, while SMBJ90CA-13-F (Diodes Incorporated) operates from -55°C and SMBJ90CA (MDD) from -50°C. Selection between substitutes depends on specific thermal environment requirements.

All parts are supplied in identical DO-214AA / SMB surface-mount packages with tape and reel packaging, ensuring direct mechanical and electrical interchangeability in PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can SMBJ90CA (MDD) be used as a direct replacement for SMBJ90CE3/TR13?

A: Yes. Both components share identical reverse standoff voltage (90V), breakdown voltage (100V minimum), peak pulse power (600W), and package configuration (DO-214AA / SMB). The clamping voltage difference (146V vs. 160V) and peak pulse current difference (4.1A vs. 3.8A) remain within acceptable operating parameters for general-purpose TVS applications.

Q: What is the difference between SMBJ90CA and SMBJ90CA-13-F?

A: Both parts are electrically identical with 90V standoff, 100V breakdown, 146V clamping, and 4.1A peak pulse current. The primary difference is manufacturer: SMBJ90CA is supplied by MDD, while SMBJ90CA-13-F is supplied by Diodes Incorporated. Operating temperature ranges differ slightly (-50°C to 150°C for MDD vs. -55°C to 150°C for Diodes Incorporated).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. SMBJ90CE3/TR13, SMBJ90CA, and SMBJ90CA-13-F are all ROHS3 compliant with REACH unaffected status, meeting current environmental and regulatory requirements.

Q: Do these parts require special handling or storage?

A: No. All three components carry MSL Level 1 classification, indicating unlimited moisture sensitivity level. Standard surface-mount component storage practices apply without moisture barrier requirements.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. All three components use identical DO-214AA / SMB package geometry and surface-mount mounting technology, enabling direct substitution in PCB layouts and assembly processes without design modification.

Q: Which substitute part offers the best low-temperature performance?

A: The SMBJ90CE3/TR13 (Microchip Technology) extends to -65°C minimum junction temperature, providing the widest low-temperature operating range. SMBJ90CA-13-F (Diodes Incorporated) operates to -55°C, and SMBJ90CA (MDD) to -50°C.

Q: What is the significance of the clamping voltage difference between parts?

A: The SMBJ90CE3/TR13 clamps at 160V maximum, while SMBJ90CA and SMBJ90CA-13-F clamp at 146V. Lower clamping voltage provides tighter transient suppression but requires verification that protected circuits tolerate the respective clamping levels. Both specifications maintain the same 90V standoff and 100V breakdown characteristics.
